Aim: How do we organize data using frequency tables, stem-and-leaf plots, and histograms?
At the end of the lesson, you will be able to...
1. organize data in a frequency table
2. draw a histogram by hand for a given set of data
3. use the graphing claculator to draw a histogram for a given set of data
4. organize data in a stem-and-leaf plot
5. compare and contrast the advantages of organizing data in frequency tables, stem-and-leaf plots, and hostograms
6. define mean, median, and mode
7. find the missing value in a data table given the mean, median, and mode.
How to create a frequency table and a histogram by hand
How to enter data in your graphing calculator
How to create a stem-and-leaf plot by hand
How to find mean, median and mode of grouped data
Classwork: Complete the following problem. Draw a stem-and-leaf and a histogram by hand. Also, graph the histogram using the graphing calculator.
Journal entry: Data points in a experiment often repeat. Frequency tables allow us to organize the data into a compact table. To find the mdeian score, the middle score must be located. How is it possible to use a frequency table to locate a median?
